The first is how rapidly and deeply the individual is breathing: Two factors each have a significant impact on the pCO2. Indirectly, the pCO2 reflects the exchange of this gas through the lungs to the outside air. PCO2 (partial pressure of carbon dioxide) reflects the the amount of carbon dioxide gas dissolved in the blood. More severe degrees of congestive heart failure.More severe degrees of pulmonary disease.PH is decreased (more acid, lower pH) with: Some degrees of congestive heart failure.PH is elevated (more alkaline, higher pH) with: Lower numbers mean more acidity higher numbers mean more alkalinity. PH is a measurement of the acidity of the blood, reflecting the number of hydrogen ions present. These measurements are often used to evaluate oxygenation of the tissues and pulmonary function. Base excess (the loss of buffer base to neutralize acid).pCO2 (partial pressure of carbon dioxide).ABG (Arterial Blood Gas) Arterial blood gas analysis typically measures:
